Height adjustable support tray apparatus

Abstract

The present apparatus relates generally to a height adjustable support tray apparatus and accessories, and more particularly to an improved height adjustable support tray apparatus to provide a portable working surface. Particularly the instant apparatus includes a unique attaching section which securely attaches the instant apparatus to the selected support structure. The instant apparatus, when attached to the applicable support structure, provides a broadly useable working surface on which to support various items. The instant apparatus includes a variety of repositioning elements thereby allowing users a multitude of adjustments of the angle and position of the working surface. The instant apparatus also includes support elements which greatly increases the load carrying capacity of the working surface over minimally supported or non-supported working services.

 an attachment section positioned on said support platform bottom side approximate said attachment edge; 
 at least one support brace positioned on said support platform bottom side, said at least one support brace interconnecting said support platform bottom side with said supporting structure; and 
 at least one support leg pivotally attached to said support platform approximate said support edge; 
 wherein said supporting structure further includes at least one handle pole extending from said supporting structure handle portion; 
 in an in-use position of said tray apparatus, 
 said at least one attachment section is positioned over said supporting structure handle portion; 
 said at least one support brace is positioned on said supporting structure at least one handle pole; and 
 said at least one support leg extends to a supporting surface; 
 wherein said attachment section includes at least one attachment channel for seating said supporting structure handle portion, and 
 said attachment section further includes at least one securing block rotatably attached to and rotatable about an axis parallel to said support platform bottom side and for releasably abutting said supporting structure handle portion when seated in said attachment section, 
 wherein in said in-use position said at least one securing block is rotated about an axis parallel to said support platform bottom side to abut said handle portion to inhibit movement of said handle portion when seated in said attachment section, and 
 wherein in a non-use position said at least one securing block is rotated about an axis parallel to said support platform bottom side to not abut said handle portion. 
 
     
     
       2. The apparatus of  claim 1  further including:
 a respositionable support brace mount attaching said support brace to said support platform bottom, 
 wherein said respositionable support brace mount allows said support brace to variably adjust it's position with respect to said support platform bottom side. 
 
     
     
       3. The apparatus of  claim 1  further including:
 a respositionable link mount which pivotally attaches each said support leg to said support platform bottom, 
 wherein said respositionable link mount allows said support leg to variably adjust it's position with respect to said support platform bottom side. 
 
     
     
       4. The apparatus of  claim 3  wherein each respositionable link mount is repositionally attached to each applicable said at least one support leg. 
     
     
       5. The apparatus of  claim 1  further including:
 a respositionable support brace mount attaching said support brace to said support platform bottom, and 
 a respositionable link mount which pivotally attaches each said support leg to said support platform bottom, 
 wherein said respositionable support brace mount allows said support brace to variably adjust its position with respect to said support platform bottom side, and 
 wherein said respositionable link mount allows said support leg to variably adjust its position with respect to said support platform bottom side. 
 
     
     
       6. The apparatus of  claim 1  further including:
 a respositionable support brace mount attaching said at least one support brace to said support platform bottom, and 
 a respositionable link mount which pivotally attaches each said at least one support leg to said support platform bottom, 
 wherein said respositionable support brace mount allows said at least one support brace to variably adjust its position with respect to said support platform bottom side, and 
 wherein said respositionable link mount allows said at least one support leg to variably adjust its position with respect to said support platform bottom side. 
 
     
     
       7. The apparatus of  claim 6  wherein each respositionable link mount is repositionally attached to each applicable said at least one support leg. 
     
     
       8. The apparatus of  claim 1  wherein each at least one support leg is variable in length. 
     
     
       9. The apparatus of  claim 8  wherein each respositionable link mount is repositionally attached to each applicable said at least one support leg. 
     
     
       10. A height adjustable support tray apparatus for support by a supporting structure having a handle portion and at least one handle pole extending from said handle portion, said tray apparatus comprising:
 a support platform having a top side, a bottom side, an attachment edge, and a support edge; 
 at least one support leg removably and pivotally attached to said support platform approximate said support edge; 
 an attachment section positioned on said support platform bottom side approximate said attachment edge, said attachment section including at least one attachment channel for seating said supporting structure handle portion, and at least one securing block rotatably attached to and rotatable about an axis parallel to said support platform bottom side and for releasably abutting said supporting structure handle portion; 
 a respositionable support brace mount attaching an at least one support brace to said support platform bottom side, said at least one support brace interconnecting said support platform bottom side with said supporting structure, 
 wherein said respositionable support brace mount allows said at least one support brace to variably adjust its position with respect to said support platform bottom side; 
 a respositionable link mount which removably, pivotally, and repositionally attaches each said at least one support leg to said support platform bottom, wherein said respositionable link mount allows said at least one support leg to variably adjust its position with respect to said support platform bottom side; 
 wherein in an in-use position:
 said at least one attachment section is positioned over said supporting structure handle portion; 
 said at least one support brace is positioned on said supporting structure at least one handle pole; 
 said at least one support leg extends to a supporting surface; 
 said at least one securing block abuts said supporting structure handle portion to inhibit movement of said supporting structure handle portion when said at least one securing block is rotated about an axis parallel to said support platform bottom side to abut said supporting structure handle portion positioned within said attachment section, and 
 
 wherein in a non-use position said at least one securing block is rotated about an axis parallel to said support platform bottom side to not abut said supporting structure handle portion.
